PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EIS00419

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
q To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions EIS0015C

q Disconnect both battery cables in advance.
q Disconnect air bag system line in advance.
q Do not tamper with or force air bag lid open, as this may adversely affect air bag performance.
q Be careful not to scratch pad and other parts.
q When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.
q When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
q Keep removed parts protected with cloth.
q If a clip is deformed or damaged, replace it.
q If an unreusable part is removed, replace it with a new one.
q Tighten bolts and nuts firmly to the specified torque.
q After re-assembly has been completed, make sure each part functions correctly.
q Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.
q Do not use any organic solvent, such as thinner or benzine.

Work Flow EIS000ZC

SBT842

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs.Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to RF-8, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
q The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
q If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
q After identifying the type of noise, isolate the noise in terms of its characteristics.The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
q Squeak --(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping
q Creak--(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
q Rattle--(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
q Knock --(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
q Tick--(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
q Thump--(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often drought on by activity.
q Buzz--(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
q Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
q Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES

DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on A
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli- B
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine. C
4) Use a floor jack to recreate vehicle "twist".
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer. D
q Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
q If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body. E
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom. F
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
G
1. Narrow down the noise to a general area.To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570,Engine Ear: J-39565 and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
H
q removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be bro-
ken or lost during the repair, resulting in the creation of new noise.
RF
q tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
q feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the J
noise.
q placing a piece of paper between components that you suspect are causing the noise.
q looking for loose components and contact marks. K
Refer to RF-6, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE L
q If the cause is a loose component, tighten the component securely.
q If the cause is insufficient clearance between components:
